摘要
综合近十多年以来在东沙群岛海域进行的反射地震资料、声纳浮标资料、双船扩长排列剖面地震测量资料及海底地震仪的折射地震资料，绘制了东沙群岛海域关于沉积层基底与地壳结构的地震地质剖面，揭示了陆架、陆坡至中央海盆之间的地壳从陆壳向洋壳的变化中，过渡带地壳具有断块构造及被拉薄的特点。
Based on reflective seismic data,sonobuoy survey,expanded spreading pronfile(ESP)survey and ocean-bottom seismometer survey(OBS)carried out in Dongsha Islands re-gion in the past ten years,seismic geologic profiles of sedimentary basement and crustalstructure are worked out.These profiles show the change of crust from continental typein the shelf to oceanic type in the central basin, and show the faulted block and thinnedcrust structure of the transitional area in the continental slope.
